EtherScore is a decentralized, on-chain reputation system for users and dApps on blockchains. It certifies the on-chain reputations of Ethereum users based on their previous actions (transaction history). User activity is represented by NFTs, which reflect the concept of collectible badges. Anyone can issue badges to identify and target specific users based on one or more minting conditions (e.g. "having done 10 swaps on Uniswap") without coding.

Metopia is a Web3 reputation-based governance platform that generates on-chain NFT identity and DAO applications, providing users with applications such as governance, rewards, and a launchpad to create a data-based user reputation system. The reputation system automatically aggregates user profiles from data protocols (RSS3, Ceramic, Moralis, The Graph, etc.). The governance platform allows users to customize DAO governance policies based on their contributions and credentials. The reward certification platform allows the community to reward members for their contributions through POAP, SBT, etc. Metopia acts as an infrastructure for creating a user-side reputation system and a governance provider based on user reputation. From membership management to community development, Metopia is creating new standards for Web3 communities.

Otterspace’s non-transferable badge protocol helps DAOs to create better incentive systems, automate permissions, and enable non-financialized governance.

Noox is a Web3 reputation platform that enables users to mint badges based on on-chain actions. These badges are Soulbound NFTs, which cannot be transferred. This allows users to have unique identifiers that may be used as their on-chain identity, unlocking new opportunities. The vision of Noox is to create a protocol that allows anyone to program rules into a badge standard (e.g. number of transactions, volume of transactions, value of transactions, type of action), and allow others to claim them if they meet the eligibility criteria.

WIW Profile is a dApp built on top of WIW Protocol, a privacy-preserving on-chain identity protocol. By doing retroactive analysis on user’s historical on-chain and off-chain data, WIW Profile generates a clear user abstraction using WIW Badges and acts as an on-chain resume solution. These badges can be customized based on the needs of the community.

Padge is a Web3 digital badge platform that can transform various achievements in life into digital badges on the blockchain through smart contracts, thereby achieving digital recording and verification of achievements.

Sismo is a modular attestation protocol that issues ZK Badges for reputation portability and aggregation. The generation process of a ZK Badge relies on zero-knowledge proofs (ZKP) and ensures user and data privacy. The ultimate goal of Sismo is to enable diverse and interoperable Badges that can be combined in creative ways, thus facilitating real innovation in authentication and reputation systems.

Short for "Proof of Attendance Protocol," POAP is the platform and infrastructure that enables the creation and storage of memories by POAP issuers and collectors. POAPs, the collectibles, are Non-Fungible Tokens (NFTs) minted under the Proof of Attendance Protocol smart contract. Each POAP is a digital record held by collectors as digital proof that they attended, or participated in, a physical, virtual, or spiritual event. Each POAP is a gift from an issuer to collectors, in celebration of a special shared memory. By minting these memories to the blockchain, collectors build a rich tapestry of tokenized experiences which unlocks a world of possibilities.
